More on this balk thing

[mcrowder]

I had a problem with that part too, especially point 3. MOST of us here are essentially anonymous - those that aren't don't need random posts on the internet to get them attention from supervisors. On point 2, I also made a comment about the possibility that R3 was potentially harmed by the lack of a stop (if there was a PB), but like you, it was not an attempt to justify the balk as much as an attempt to debunk the "advantage/disadvantage" argument.
